MR* Series Motor

High Torque Fixed Displacement Radial Piston Motor, Up to 9000 cm³/rev – 550 in³/rev.

The MR* Series hydraulic fixed displacement motors ensure superior reliability and extended lifetime, supported by their high mechanical efficiency, high starting torque and advanced low friction and wear technology.

Motors can be customized by selecting different types of shafts, speed sensors, seals, and connection flanges. Optional accessories include gearboxes and parking brakes. Furthermore, MR motors can be equipped with optional built-in manifold blocks (cross relief, anti-cavitation, flushing and drain valves) to suit the customer needs

These radial piston fixed displacement hydraulic motors have been specifically engineered for high mechanical and volumetric efficiency over a wide range of speed and torque. MR motors are combined into 11 different frame sizes, corresponding to 41 standard displacements available, from 33 cc/rev to 9000 cc/rev.

Due to their special design, the MR motors deliver their maximum performance when the application requires high torque values. The MR motors combine precise and smooth movements, both at low speed and during acceleration and deceleration transitions.
